What is the blood made of?The blood is made up of:· Red blood cells These make up 40-45% of the blood and give it the red colour. Their function is to carry oxygen from the lungs throughout the body.· White blood cells Their job is to fight infection and there are three different types: granulocytes, lymphocytes, and monocytes.· Platelets These cells help blood to clot, they clump together to form a clot or scab. These cells are transported by Plasma. Plasma also transports hormones, nutrients, clotting agents and waste products that need to exit the body.…read more

Slide 3

RED BLOOD CELLS These cells contain a molecule called haemoglobin that carries the oxygen. These molecules loosely bind with the oxygen that is in the lungs. The blood carries the molecules through the capillaries where there is little oxygen and the haemoglobin sheds the oxygen allowing the bodies cells to absorb it.White Blood Cells There are three different types of Granulocytes: neutrophils, eosinophils, and basophils.· These kill invading bacteria by ingesting them and then digesting them.· These kill parasites and are involved with allergic reactions.· These are also involved with allergic reactions. There are two different types of lymphocytes: T cells and B lymphocytes.· These produce antibodies which destroy foreign bodies.· These direct the activity of the immune system. Monocytes enter body tissue and turn into cells called macrophages and eat foreign bacteria and destroys damaged and dead cells of the body.…read more
